摘要
比较了TA4纯钛材电化学抛光表面和阳极氧化表面的形貌、抗腐蚀性能、微动摩擦磨损性能和生物活性。结果表明,与阳极氧化表面相比,电化学抛光表面具有较多纳米尺度孔穴(孔穴总数较低),较低的表面粗糙度(低约一个数量级),较低的抗腐蚀性能(后者的腐蚀速率比前者的稍大),较低的摩擦系数(0.134vs.0.286),较差的耐磨性能,以及较高的生物活性(模拟体液中Ca-P层的生长速率)。
The surface morphology,corrosion resistance,fretting friction and wear properties and bioactivity of electrochemical polished surface and anodic oxidized surface on TA4 pure titanium were investigated.The results show that compared to the anodic oxidized surface,the electrochemical polished surface has more nano-scale cavities(fewer total cavitities),lower surface rougness(about an order lower),lower corrosion resistance,lower friction coefficient(0.134 vs 0.286),worse wear resistance,and higher bioactivity(growth rate of Ca-P layer in simulated body fluid).
